Niet te verwarren met infiltratiesnelheid. Het hele proces en het verschil tussen infiltratiesnelheid en percolatiesnelheid:
"Infiltration and percolation are two related but different processes describing the movement of moisture
through soil. Infiltration is defined as the downward entry of water into the soil or rock surface (SSSA,
1975) and percolation is the flow of water through soil and porous or fractured rock. In hydrologic
modeling, these two processes are usually modeled separately. Infiltration rate is the rate at which a soil
under specified conditions absorbs falling rain, melting snow, or surface water expressed in depth of
water per unit time (ASCE, 1985). Percolation rate, although more difficult to measure directly,
represents the rate at which soil moisture moves down through the soil or permeable rock."
